Gmail version 2.0:Google has just released a major update to its Gmail iOS app, introducing multiple account support, a new look that appears to be partly inspired by its Sparrow acquisition, search predictions and much more. The update also brings interactive Google+ posts support, an infinite scroll inbox, new welcome screen, and the ability to respond to Google Calendar invites. Google walked through some of the new features of the overhauled Gmail app in a blog post noting the app was six months in the works:

Six months ago, our team set out to completely rebuild the Gmail app for iPhone and iPad to give you you a faster, sleeker, and easier experience on iOS. The result? Version 2.0. With version 2.0 of the app, you’ll get a totally new look and feel, plus a bunch of improvements like profile pictures in messages, numerous new animations from swivels to transitions and infinite scrolling in the message lists.

Looks like the new Gmail app for iOS is still rolling out on iTunes. If you're having trouble, try again later.

Kindle version 3.5: Amazon previously rolled out its X-Ray feature, which used to be exclusive to Kindle devices, to iOS devices back in October. At the time, it was only making the feature available for textbooks on iOS. Today, Amazon has updated the Kindle iOS app to extend the X-Ray to all books. The update also includes “Manga Image Rendering Improvements”:

• X-Ray for Books – see the “bones of the book”. X-ray helps you learn more about notable characters, places, and phrases with descriptions from Shelfari.com and Wikipedia.
